In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. [6] Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018. [7]
Studies of liquefaction features left by prehistoric earthquakes, called paleoliquefaction or paleoseismology, can reveal information about earthquakes that occurred before records were kept or accurate measurements could be taken. [21] Soil liquefaction induced by earthquake shaking is a major contributor to urban seismic risk.

The instability is, however, only latent because it is dependent on liquefaction to become real. The process of liquefaction implies a considerable to almost complete loss of yield strength of the layer involved. This important prerequisite has been appreciated since Sorby in 1908 (and later on by Shrock in 1948), who recognized the ...
Paleoliquefaction is any liquefaction features attributed to seismic events occurring before measurements or written records were kept of earthquakes. [1] The study of these features can reveal a great deal about the seismicity of regions where large earthquakes happen infrequently. This is a subset of the broader field of paleoseismology.
When the ground materials become saturated with enough water, they will start flowing (soil liquefaction). Its speed can range from being barely noticeable to rapid movement. The velocity of the flow is dictated by water content: the higher the water content is, the higher the velocity will be. [1]
The term ground failure is a general reference to landslides, liquefaction, lateral spreads, and any other consequence of shaking that affects the stability of the ground. This usually takes place as an after-effect of an earthquake , and is one of the major causes of destruction after an earthquake.
Sand boils can be a mechanism contributing to liquefaction and levee failure during floods.Boil refers to the visible "boiling" movement of coarse sand grains retained in the hole even as finer particles (silts and fine sands) are carried out and deposited on the apron around the boil hole.
